APPARATUS FOR COMPOUNDING AND MIXING GLASS BATCH.

SPECIFICATION forming part of Letters Patent No. 520,138, dated May 22,1894.

Application filed February 25, 1893. Serial No. 463,779. (NomodeL) Toall whom it may concern.-

Be itknown that I, ROBERT DRALLE, a resident of Berlin, in the Kingdomof Prussia and Empire of Germany, have invented a new and usefulImprovement in Apparatus for Compounding and Measuring Glass Batch; andI do hereby declare the following to be a full, clear, and exactdescription thereof.

My invention relates to measuring apparatus, its object being to providean apparatus by which materials or ingredients which go to make updiiferent compounds may be meas- 1tired out automatically in the desiredproporions.

To this end my invention comprises, generally stated a hopper to receivethe material, a spiral screw or conveyor arranged at the lower end ofsaid hopper, and mechanism for imparting an intermittent rotary movementto said spiral screw or conveyor whereby a certain proportion of thematerial in said hopper is ejected therefrom by said spiral screw orconveyer to a suitable receptacle, and mechanism for increasing or dimnishing the amount of rotation of said spiral screw or conveyoraccording to the proportion of the material desired to be ejectedtherefrom in making up the entire mixture.

My invention further consists in the arrangement of two or moreautomatic measuring machines with reference to a common conveyor wherebythe materials are fed in their proper proportions to a suitable mixingreceptacle.

To enable others skilled in the art to make and use my invention, I willdescribe the same more fully, referring to the accompanying drawings, inwhich- Figure l is a front view partly in section of my improvedapparatus. Fig. 2 is a side view thereof, and Fig. 3 is a plan View ofseveral measuring machines feeding into a common conveyer connected witha suitable receptacle.

Like letters and figures indicate like parts in each of the views.

The measuring apparatus consists of any suitable frame composed of thestandards a connected by the cross braces 11 and having the top piece 0which supports the hopper d. The hopper d is provided with the box e atthe lower end thereof and communicating with said box is the cylinder f.And in order to provide a means of conveying away the material fed fromthe hopper by the spiral screw h, as will -more fully hereinafterappear, a cylinder f containing the spiral conveyer f may be arranged tocommunicate with the cylinder f. A shaft g is journaled in the framewithinthe cross braces b, said shaft carrying the spiral screw orconveyer h which is adapted to rotate within the box e and the cylinderf, said cylinder being accurately bored out so that said spiral screw orconveyor fits snugly therein. One end .of the shaft g projects beyondthe frame of the apparatus and has secured thereto the ratchet wheel i.A lever j provided with the bifurcated end It is fitted loosely on theshaft g, the bifurcated end it of said lever j engaging with said shaftg on both sides of the ratchet wheel a. A pawl or ratchet Z is mountedon the pin m passing through the bifurcated end k of the lever j, saidratchet or pawl being adapted to engage with the teeth of the ratchetwheel '5. Surrounding the lever j is the sleeve n adapted to move up anddown on said lever and to be secured at any desired point thereon bymeans of the set screw 0. The sleeve n is formed with the tongue 15thereon'to which is pivoted one end of the connecting rod g, said rodbeing pivoted at its opposite end to an eccentric r, mounted on thedriving shaft 3.

The niecha fii'sinfol'tmparting rotary movement to the spiral screw orconveyer may be changed and otherforms of mechanism substituted toproduce the same effect without going beyond the scope of my invention,therefore I do not confine myself to the particular mechanism set forthand described.

The raw material to be measured is introduced into the hopper d whenceit passes down into the box 6. Power is then applied to drive the shaft.3 and the eccentric 7 carried thereby. As the eccentric r revolves inthe direction of the arrow, Fig. 2, the rod q connected theretofollowing the line of rotation of said eccentric imparts a reciprocatingmovement to the lever j. By this reciprocat- 1ng movement, the pawl Zengaging with the 5 ratchet wheel 71 imparts an intermittent rotarymovement to said ratchet wheel '6 and conseuently to the shaft g. Thuswhen the leverj 1s drawn by the connecting rod q toward the left, thepawl Z will drive the ratchet wheelt' 1n the same direction, but whenthe lever j returns to its former position, by thefurther rotation ofthe eccentric r the pawl Z moves over the teeth of the ratchet wheeliwithout imparting any movement to said wheel. The r 5 spiral screw orconveyer on the same shaft 9 has imparted to it a like intermittentmovement whereby upon each movement of the ratchet wheelc' apredetermined proportion of the material introduced into the hopper isejected from the cylinder f into the cylinder f or other suitablereceptacle. I

The apparatus is intended principally for the compounding of mixtureswhich are made up of several different ingredients, such as in makingup' what'is termed the batch in the manufacture-of glass. Forillustration, a common batch 'for bottle glass is made up of one hundredparts sand, 33.3 parts lime, and twenty parts soda, and, inorder to makethis batch with the proper proportion of the above ingredients, three ofthe above doscribed'machines are placed side by side, as

shown in Fig. 3, the feeds of the several ma-- chines being adj usted inthe proper ratio. To obtain this proper ratio, the lever j may haveformed thereon a graduated scale whereby upon moving the sleeve 1 fromone point to another of said scale the alternation in the rotarymovement of the spiral screw or conveyer can be'determined by a fixedstandard. As above stated, three machines, 1 2 3, are placed side byside and the ingredients ejected from'each machine in the properproportions may be fed into a common transport screw f and carried to asuitable receptacle t where they may be properly mixed. If it is desiredto change the proportions or vary them for compounding other mixtures,it is only necessary to adjust the sleeve 91. at the proper point on thelever j to produce the required change.

The spiral screw can be set in any position, horizontal, perpendicular,or otherwise, so that I do not confine myself to its employment in'theparticular position shown.

What I claim as my invention, and desire to secure by Letters Patent, is
